What's wrong with my syntax?

Thanks Ned,

That took care of that error but I'm still getting an undefined error. Do you know why this URLRequest is not loading the .swf? Lines 21 and 22

//THIS IS THE PRELOADER CONTAINER THAT LOADS THE INTERACTIVE
//STRATEGY MAP (Interactive_StrategyMap.swf).

// CREATE A NEW LOADER OBJECT TO HOLD THE LOADED CONTENT
var holder:Loader = new Loader();
addChild(holder);

// CREATE EVENT HANDLERS TO TRACK THE LOADING PROGRESS
// AND TO TRACK THE COMPLETION OF THE LOADED CONTENT
holder.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onLoading);
holder.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
function onComplete(e:Event):void {
this.loadingClip.visible = false;
}
function onLoading(e:ProgressEvent):void {
var pcent:Number = e.target.bytesLoaded / e.target.bytesTotal * 100;
loadingClip.loadingText.text = int(pcent) + "%";
}

// LOAD THE EXTERNAL CONTENT
holder.load(new URLRequest("Interactive_StrategyMap.swf" + "?random=" + Math.random()));
trace(holder.load(new URLRequest("Interactive_StrategyMap.swf" + "?random=" + Math.random())));
